OIL-BURNER.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed MayS, 1911. Serial No. 625,883.

To all whom it may concern:

Be it known that I, wWLLIAM T. Casnon'r, a citizen of the United States7 residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to oil burners of' that. type employing steam as a .means for atomizing the oil, and has for its objectI to produce an oil burner which will operate efficiently, reliably and economically.

To this end the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing in which:-

Figure 1, is a vertical longitudinal section of an oil burner embodying my invention. Fig. 2, is a section on the line II-II of Fig. 1. Fig. 3, is a section on the line III-III of Fig. 1.

In the said drawing where like reference characters identify corresponding parts, 1 indicates a suitable nblock or support provided near its lower end with a threaded passage 2 and near its upper end with a smooth or non-threaded passage 3.

4 is a pipe leading 'from an oil reservoir or tank (not shown) and screwed at its front end in passage 2.

5 is an alined pipe which practically .forms a continuation of pipe 4 and is screwed at. its rear end into passage 2.

6 is a threaded sleeve paralleling pipes 4 and 5 and extending slidingly through pas sage 3, and engaging said sleeve is a pair of hand-nuts 7 susceptible of adjustment and adapted for engagement with the opposite sides of t-he block or support to secure the sleeve atthe desired point of adjustment in passage 3.

8 is a pipe leading from the steam dome or other chamber of a boiler and said pipe is screwed into the rear end of sleeve 6.

9 is a pipe alined with pipe 8 and in conjunction with the sleeve, constituting an extension for said pipe, the rear end of said pipe 9 being screwed into said sleeve.

10 is a head or burner tip whose upper face is preferably flat, as shown, and 11 indicates the chamber of said head or tip, and from said chamber oil is adapted to escape to the upper or flat face by way of the orfices 12, which by preference constitute a V-shaped series as shown clearly in Fig. 2. Rearward of said orifices the upper wall of the head or tip is provided with a longitudinal dove tail grooif'e 13, and below said groove the rear wall is provided with a threaded opening 14 receiving the threaded front end of' pipe 5.

15 indicates a steam nozzle fitting flatly upon the oil head or tip 10, and provided with a chamber 1G and a plurality of forwardly-converging and downwardly-inclined jet openings 17, through which steam will be discharged downwardly and forwardly against the upper face of the oil head or tip. By preference the jet openings are so arranged that the jets of steam thereof will intercept the oil as it escapes upwardly through orifices 12 in order that such oil may be more effectually atomized, as the force of the steam jets tends to tear or disrupt and finely divide the oil as it emerges from the said orifices, and to accomplish this purpose the openings 17 extend in such direction that the jets of steam in issuing' therefrom shall strike the outer edges of' the streams of oil issuing up through orifices 12, and thus tend to give such oil a whirling movement to effect a more rapid atomization thereof than if the jets of steam impinged centrally against such streams of oil as will be readily understood. The steam nozzle is provided with a depending longitudinal dove tail rib 18 engaging the groove 13 and guarding against independent lateral movement of the tip or nozzle. It also guards against independent upward or downward movement of the tip or nozzle, and the latter is provided in its rear wall with a threaded opening 19 receiving the threaded front end of pipe 9.

In practice pipes 4 and 8 will be provided with valves (not shown) because of common and well known use for controlling the passage of oil and steam to the tip and nozzle respectively, and the oil will be supplied under pressure, preferably by gravity feed, as is common in oil burner construction.

Assuming that the parts are arranged as shown in Fig. 1, the operation is started by opening said valves and as the steam issuing from openings 17 atomizes the oil issuing from orifices 12, a combustible mixture is produced which is ignited in any suitable 'manner, the flame by reason of the peculiarV forwardly on the sleeve to permit the latter,

with the nozzle and pipe 9 to be slid rear- Wardly until said nut arrests such movement by engagement with the front side of the block or support, and if it is desired to clamp the nozzle in its new position the rear nut is screwed forwardly upon4 the sleeve until it is arrested by engagement with the rear side of said block 0r support, it being understood that pipe 8 is capable of movement with the sleeve to accommodate the adjustment thereof, and that the sleeve is located exterior to the furnace or combustion chamber (not shown) in order that the operator may conveniently manipulate said nuts for adjustment purposes. To reduce the size of the flame the operation described is reversed, it being noted that the rib by engagement with the front end of groove 13 will limit the forward adjustment of the nozzle before the front extremity thereof passes beyond the orifice 12 at the apex of the V-shaped series so that it will be impossible to accidentally extinguish the flame.

I have found in practice the combustion is so perfect with this burner that only a minimum quantity of oil is necessary to produce a maximum heat and in this connection it is desirable to state that the tip becomes so highly heated that the oil is substantially vaporized by the time it emerges from the orifices 12.

From the above description it will be apparent that I have produced an oil burner of simple, durable and inexpensive construction, embodying the features of advantage enumerated as desirable, and it is to be understood that the burner is susceptible of modification in minor particulars without departing from the spirit and scope or sacrificing any of the advantages of the appended claims.

What I claim is: i

1. An oil burner, comprising a tip having a substantially fiat upper face and a V- shaped series of orifices for discharging oil upwardly and upon said upper face, the apical opening of said series of orifices being nearest the front end of the tip, and a nozzle above the said tip and provided with a series of forwardly-converging and downwardly-inclined jet openings for discharging a fiuid against oil issuing upward from said orifices.

2. An oil burner, comprising a support provided with a passage, a threaded sleeve extending slidingly through said passage, a pair of nuts engaging the sleeve and the opposite sides of the support, a steam supply pipe connected to the rear end of the sleeve, a pipe connected to the front end of the sleeve, an oil supply pipe secured to the support and extending parallel with the first-named pipes and sleeve, a hollow tip secured to the front end of the oil supply pipe, provided with a substantially flat upper face and with orifices for discharging oil upwardly and upon said face, a nozzle resting upon said tip and secured upon the front end of the pipe secured to the front end of the sleeve and provided with forwardly converging and downwardly -inclined jet openings for discharging steam against the oil issuing upwardly from said orifices.

In testimony whereof I aflix my signature, in the presence of two witnesses.
